Disk brakes might be useful

Snipped Well, the rims on my 1st MTB were nearly shot after the first 1000mi of foul weather riding. Most of the time I reached on on soggy winter trail rides there was this goose bump eliciting sandpaper noise. Needless to say, the next MTB had disc brakes and none of this is happening now. Why should people put up with inferior components if there are better ones that even reduce cost per mile over the years? -- Regards, Joerg http://www.analogconsultants.com/ Indeed! Why should I put up with the cost and hassle of replacing discs (and my bicycles)when all my bicycles braking systems are perfectly fine for MY needs? Most of my bicycles are of circa mid-1980s vintage and as I said before I have yet to wear out a rim because of braking. Even my MTB that I use for 2 weeks long remote mining/logging roads touring has never needed a rim replaced. YMMV and usually does. Cheers |

What I mean by "drastic" is people like Joerg who have to replace a rim because it was worn through by rim brakes withing 1000 miles. Based on MY experience riding on dirt roads, touring with 40 pounds of gear on logging roads for 2 weeks at a time, and riding in the rain and riding through the winter 1000 miles seems quite a low number of miles for a pair of rims. I wonder if Joerg rides the brakes? Cheers |

I wonder if Joerg rides the brakes? I don't but a cycling friend does and it's weird. He rode a very powerful Honda motorcycle when younger but is afraid to get above 10mph downhill on singletrack or 15mph on roads while on a bicycle. Luckily he has disc brakes on all his bikes so it isn't a big issue. We have lots of decomposed granite, some of it in the shape of almost a powder. The heavier a trail is traveled the more powder there is. The last remaining bits are crushed by horses. Decomposed granite mixed with mud is an almost ideal abrasive paste. It is a horrible sound similar to holding a piece of aluminum onto a belt sander. -- Regards, Joerg http://www.analogconsultants.com/ |

On the way back it was about 25F (-4C), below freezing, but hardly frostbite weather. The sun was shining, the wind was blowing, the crows were singing merrily to keep the seagulls in their place. The streets were mostly clear, at least in the travel lanes, but were damp with melted brine. We haven't had much snow this year, and local governments are dealing as best they can with the dire prospect of a road salt budget surplus. The brine tends to get tracked into the mean right tire track, forming a dark stripe, which is where I rode a great deal of the time. To the right were piles of ice and snow, patches of crusty salt, dog**** popsicles and cigarette butts. To the left it was already a bit hard for drivers to pass. Two blocks from home, having not touched the brakes in quite a while, I meant to slow for a left turn, and applied the brakes. Just perceptible slowing obtained, even when squeezing hard. This was a little disappointing, not what most would expect from brakes at all. Unlike rain, the problem didn't go away as water was wiped from the rims -- it stayed crappy until I almost missed my turn in the neighbor's front yard. I remember many snow rides from Europe. Sometimes I had to let the pads gently rub on the rims well before an intersection to make sure there'd be some stopping power. Rim brakes are about as "modern" as those wood blocks against the wheels of a chuckwagon. Also, winter rides tend to eat rims. So do rain rides. Replacing a brake rotor takes five minutes (with coffee) and about $20-$25, changing out a rim is a different story. When I got home I looked at the rims. They were coated in white frosty stuff that looked a lot like snow, but stuck much more resolutely. Not normally much for washing bicycles, I spent a few minutes cleaning off the frost and salt.

Rims are a wear item. -- This morning the normal Tuesday ride was scheduled until I emailed them that the temperature was 2 degrees above freezing in the end town and that in between there was probably ice on the shady downhills. Suddenly they changed their minds. Didn't matter to me since I had to go to the Dentist and I'm still too numb to drink a cup of coffee. If your buddies knew how they were embarrassing California on an international forum they might butch up a little. |
